  • The Basics: ORP and Free Chlorine Monitoring
    5/13/2014

    Oxidation Reduction Potential or Redox is the activity or strength of oxidizers and reducers in relation to their concentration. Oxidizers accept electrons, reducers lose electrons. Examples of oxidizers are: chlorine, hydrogen peroxide, bromine, ozone, and chlorine dioxide. Examples of reducers are sodium sulfite, sodium bisulfate and hydrogen sulfide. Like acidity and alkalinity, the increase of one is at the expense of the other.

    Osmosis is the phenomenon of lower dissolved solids in water passing through a semi-permeable membrane into higher dissolved solids water until a near equilibrium is reached.

DRINKING WATER PRODUCTS

The WATERFLUX 3070 is a battery powered electromagnetic water meter for use in water abstraction wells, district metering areas (DMA) and custody transfer measurement of potable water (MI-001, OIML R49). With optional pressure and temperature sensors, the meter can also be used for leak detection, quality control and pressure management systems. 

This sealed “junction box” receives the special “vented” type sensor cable from a Druck sensor and connects to a less expensive, non-vented, proprietary sourced instrument cable. It allows barometric reference pressure to enter the enclosure while providing a block to water/humidity entering and condensing in the assembly.

The C3 is a rugged, three-channel submersible fluorometer and datalogger that allows simultaneous detection of multiple parameters such as chlorophyll, CDOM, and phycocyanin. Its compact size and versatile design make it ideal for profiling, discrete sampling, and autonomous platforms. Rated to 600 meters, the C3 gives researchers a flexible, reliable tool for multi-parameter water quality studies.

While dosing challenging chemicals can be tricky for operators, there are a range of technologies that will help mitigate problems and ensure smooth, accurate, and dependable chemical dosing.

ECT2 has ready-to-run Pilot PS Series for rapid deployment and implementation around the world.

Designed to transform mechanical meters into communication data points, Itron's Cyble communication modules enable remote reading and monitoring of water meters on-site events.

Water scarcity challenges are growing. Manufacturing the products used in our daily lives consumes a large amount of water. Reusing treated wastewater provides the most sustainable source of clean water.

The Orange County Water District (OCWD) has long been an innovative leader in indirect potable reuse. An integral component of its Groundwater Replenishment System (GWRS) – a 100 million gallon per day advanced water purification facility – is reverse osmosis membrane technology.

ABOUT DRINKING WATER

In most developed countries, drinking water is regulated to ensure that it meets drinking water quality standards. In the U.S., the Environmental Protection Agency (EPA) administers these standards under the Safe Drinking Water Act (SDWA)

Drinking water considerations can be divided into three core areas of concern:

  1. Source water for a community’s drinking water supply
  2. Drinking water treatment of source water
  3. Distribution of treated drinking water to consumers

Drinking Water Sources

Source water access is imperative to human survival. Sources may include groundwater from aquifers, surface water from rivers and streams and seawater through a desalination process. Direct or indirect water reuse is also growing in popularity in communities with limited access to sources of traditional surface or groundwater. 

Source water scarcity is a growing concern as populations grow and move to warmer, less aqueous climates; climatic changes take place and industrial and agricultural processes compete with the public’s need for water. The scarcity of water supply and water conservation are major focuses of the American Water Works Association.

Drinking Water Treatment

Drinking Water Treatment involves the removal of pathogens and other contaminants from source water in order to make it safe for humans to consume. Treatment of public drinking water is mandated by the Environmental Protection Agency (EPA) in the U.S. Common examples of contaminants that need to be treated and removed from water before it is considered potable are microorganisms, disinfectants, disinfection byproducts, inorganic chemicals, organic chemicals and radionuclides.

There are a variety of technologies and processes that can be used for contaminant removal and the removal of pathogens to decontaminate or treat water in a drinking water treatment plant before the clean water is pumped into the water distribution system for consumption.

The first stage in treating drinking water is often called pretreatment and involves screens to remove large debris and objects from the water supply. Aeration can also be used in the pretreatment phase. By mixing air and water, unwanted gases and minerals are removed and the water improves in color, taste and odor.

The second stage in the drinking water treatment process involves coagulation and flocculation. A coagulating agent is added to the water which causes suspended particles to stick together into clumps of material called floc. In sedimentation basins, the heavier floc separates from the water supply and sinks to form sludge, allowing the less turbid water to continue through the process.

During the filtration stage, smaller particles not removed by flocculation are removed from the treated water by running the water through a series of filters. Filter media can include sand, granulated carbon or manufactured membranes. Filtration using reverse osmosis membranes is a critical component of removing salt particles where desalination is being used to treat brackish water or seawater into drinking water.

Following filtration, the water is disinfected to kill or disable any microbes or viruses that could make the consumer sick. The most traditional disinfection method for treating drinking water uses chlorine or chloramines. However, new drinking water disinfection methods are constantly coming to market. Two disinfection methods that have been gaining traction use ozone and ultra-violet (UV) light to disinfect the water supply.

Drinking Water Distribution

Drinking water distribution involves the management of flow of the treated water to the consumer. By some estimates, up to 30% of treated water fails to reach the consumer. This water, often called non-revenue water, escapes from the distribution system through leaks in pipelines and joints, and in extreme cases through water main breaks.

A public water authority manages drinking water distribution through a network of pipes, pumps and valves and monitors that flow using flow, level and pressure measurement sensors and equipment.

Water meters and metering systems such as automatic meter reading (AMR) and advanced metering infrastructure (AMI) allows a water utility to assess a consumer’s water use and charge them for the correct amount of water they have consumed.
